• Add input fields for:
  • amount
  • source currency
  • target currency
• Add a convert button
• Display the converted result
• Connect the GUI to existing conversion logic where possible

Acceptance criteria

• Tkinter window opens successfully
• User can enter amount, source currency and target currency
• Convert button triggers conversion logic
• Result is displayed in the GUI
• Basic error message is shown for invalid input
